[sumo-user] Error with flows definition in the development version

[Lara Codeca <lara.codeca@xxxxxxxxx>]

Hello Everyone,

I'm a maintainer of a couple of open-source tools related to SUMO.

With SUMO 1.6 my small toy scenario works fine.

With the devel version was working fine until yesterday. Something has changed in the last 3 weeks, but I don't know what.

Nonetheless, the problem is with the flow definition, and it makes me think that this problem is going to break a lot of scenarios already available.

I suppose something major has changed, but I cannot find it associated with the Issues already open.

Version: Eclipse SUMO sumo Version v1_6_0+1493-02f4414fa4

Error: sumo sumo.cfg.xml 

Loading configuration ... done.
Error: no declaration found for element 'flows'
 In file 'flows.xml'
 At line/column 3/8.
Quitting (on error).

Attached you can find the 3 files required to run the scenario.

In case the attachments are blocked, the example is available at https://github.com/lcodeca/rllibsumoutils/tree/master/example/scenario.

Thanks all for your time.

All the Best,

Lara
